SPECIFICATION forming part of Letters Patent No. 74:0,45 5, datedOctober 6, 1903.

Application filed January 13, 1903. Serial No. 138.1937. (No model.) Y

To @ZZ whom it may concern:

Be it known that 1, WILLIAM H. MOON, a citizen of the United States,residing atMuncie, in the county of Delaware and State of Indiana, haveinvented a new and useful Blowpipe-Rest, of which the following is aspecication.

My invention is an improvement in bloW- pipe-rests, the object ot myinvention being to provide a suitable support forfglass-blowers,especially those engaged in the manufacture of window-glass. The rest isdesigned to be placed on the beam of a small swinging crane arrangeddirectly in front of a furnace. When a cylinder of glass has been blown,it usually presents an irregular surface. It is therefore passed intothe furnace, the weight of the cylinder being supported by my rest,which comprises two ball bearing wheels mounted tandem-like, thecylinder resting between the wheels. By revolving the cylinder at a redheat it soon becomes of a uniform diameter, the irregularitiesdisappearing. With the old solid fork it was diiicult to turn thecylinders, which are of considerable weight. Y

In the accompanying drawings, Figure'l is a perspectivev View of myrest. Fig. 2 is a side elevation, parts being in section. Fig. 3 is asectional view taken transversely through one of the rollersthe axle andballs being in elevation. p

In carrying out my invention -I employ a bracket having a stern A,carrying at its upper end a solid horizontal plate B, having sides B',from which project upward from each end of a side two sets ofparalleLarms B2,

, these arms being rounded and thickened at their upper ends. A web B3,formed centrally on the upper part of the plate, connects the two sides,which have a curved upper surface between the arms. The thicky enedupper portion of the arms is transversely perforated and threaded, theperforations on one side of the rest being of greater diameter thanthose in the arms on the opposite side. An axle C, having a threaded endand head and a smooth intermediate portion, connects the front and reararms, respectively, the head fitting in the larger perforation. Aninteriorly-threaded collar C is secured on the threaded end portion ofthe axle and tits tightly against the inner face of the arm on thatside. This collar is cut out at C2 adjacent its inner edge. A similarnon-threaded -collar C3 is positioned on the smooth portion Yof the axleadjacent the head and is held against rotation by a lng C4, projectinginto a recess C5, formed in the arm B2.

It is understood that the above description lof the collars secured onone of the axles applies to'those on the other collar.

0n each axle between the collars is mounted a wheel D, and each wheelhas an annular groove D', the upper edge of the groove projectingoutward and forming a iange D2, which encircles the inner cut-out edgeof the collars, a groove and flange being formed on each side of thewheel. Within the grooves held between the wheels and the collars arethe antifriction-balls E.

The partsA and B are cast in one piece,

and the wheels are formed with a hard chilled 'surface to enable them towithstand the intense heat imparted to them by thev glass.

When all the parts described are assembled together, they are held inplace by a nut E,

threaded on the end of each axle.

Having thus fully described my invention, what I claim as new, anddesire. to secure by Letters Patent, is-V 1. vA blowpipe-rest comprisinga bracket having a downwardly-projectingstem, two pairs ofupwardly-extending arms, each pair of arms carrying a non-revolubleaxle, a roller mounted on each, collars on each side of the rollers, andantifriction-balls between the collars and their respective roller.

2. A blowpipe-rest comprising a bracket having a stern, a plate at theupper end of the stem, arms projecting upward from each corner of theplate, said arms having threaded perforations therein, axles threadedadjacent each end secured in the perforations of the arms and having asmooth intermediate por tion, rollers mounted thereon, collars on eachside of said rollers, and antifrict-ion-balls between the rollers andcollars. I

3. A device of the kind described, comprising a bracket having recesses,axles having threaded heads and ends `mounted in the bracket, rollershaving annular grooves on each side and an outwardly-extending flangearound the grooves, interiorly-threaded collars on the threaded endportions of the axles having their inner edges cut away, collars on thesmooth portion of the axles, lugs on said collars projecting` into therecesses, the said rollers being mounted on the axles between theeo1la1s,'and antifrietion-balls arranged in f the grooves of the rollersand held in position by the oollarsrand llanges.
